Multi-species Gas Analyzer Prismatic2 Multi-species Gas Analyzer Prismatic2

Overview

Based on Cavity Ring-Down Spectroscopy (CRDS), TigerOptics Prismatic2 multi-species gas analyzer can measure the sub-ppb level of gas species with absolute accuracy, proven reliability, and fast response in one compact and easy-to-use device. With a combined electronics and sensor module that can simultaneously measures multiple analytes in a wide variety of background gases, the Prismatic2 offers precise analysis over a vast dynamic range.

Application

  • Quality control for laboratory analysis
  • On-line gas monitoring
  • R&D for gas and chemical industries

Features

  • NIST traceable
  • High sensitivity, high accuracy, high reliability, high speed of response
  • Compact, ease of operation, no periodic replacement/maintenance
  • Analytes: H2O, CO, CO2, CH4, NH3, HCl etc.
  • Wide dynamic range
  • Simultaneous multi-species detection
  • Ethernet, isolated 4-20 mA and RS-232 connectivity

Cavity Ring-Down Spectroscopy(CRDS)

  1. 1.A Continuous Wave (CW) diode laser emits a directed beam of light energy through an ultra-high reflective mirror into the absorption cell (cavity).
  2. 2.The light reflects back and forth between two ultra-high reflective mirrors multiple times, up to a total path length of 100 kilometers.
  3. 3.Once the photodiode detector “sees” a preset level of light energy, the light source is shuttered or diverted from the cavity.
  4. 4.On each successive pass, a small amount of light or ring-down signal emits through the second mirror and is sensed by the light detector.
  5. 5.Once the light "rings down", the detector achieves a point of zero light energy in milliseconds, and the measurement is complete.
